ABSTRACT:
An anatomical multilayer seat for use on a bicycle or the like. The seat comprises a formed substantially rigid shell covered by a flexible cover sheet and having a layer of soft encapsulated gel material provided between the cover shell and the seat shell. The encapsulated gel layer is constrained against any appreciable lateral movement while permitting only limited deflection of the gel during use by a lower formed foam layer provided between the shell and the cover sheet to produce a controlled graduated support for the rider. If desired, a second upper layer of a resilient material can be advantageously provided between the gel layer and the cover sheet of the seat for encapsulating the gel layer. The invention also includes a method for making the anatomical multilayer seat.
